The filmmaker behind the Kony 2012 viral video who was detained by police in San Diego last week after roaming the streets naked and screaming incoherently has been diagnosed with brief reactive psychosis.

“(This is) an acute state brought on by the extreme exhaustion, stress and dehydration,” his wife says Danica Russell said in a written statement.

“Though new to us, the doctors say this is a common experience given the great mental, emotional and physical shock his body has gone through in these last two weeks.”

Released two weeks ago by the charity Invisible Children, the Kony 2012 video received an unprecedented amount of positive and negative attention.

Viewed more than 100 million times online, the 30-minute film lobbies for U.S. intervention to capture Ugandan warlord Joseph Kony, the head of the Lord Resistance’s Army rebel group.

Kony, along with the LRA, once terrorized northern Uganda, allegedly kidnapping children, mutilating them and turning them into soldiers. But critics were concerned the film oversimplified the region’s issues, and overlooked the likelihood that Kony’s capture would end in bloodshed.

Invisible Children and Jason Russell were forced to defend the film when questioned about their motives and messages, and the charity’s financial transparency.

Screenings of the film were cancelled in northern Uganda after a crowd of viewers in the city of Lira grew angry about the film’s portrayal of the Ugandan government, which has been accused of its own human rights abuses.

The charity took another hit when Mr. Russell was detained and transported to a medical facility last Thursday after witnesses told police they saw the 33-year-old ranting about the devil on the street, wearing no clothes.

In her statement, Mr. Russell’s wife says her husband’s behaviour had nothing to do with drugs or alcohol.

“Jason will get better. He has a long way to go, but we are confident that he will make a full recovery,” she said.

“He is, and will remain, under hospital care for a number of weeks; and after that, the recovery process could take months before he is fully able to step back into his role with Invisible Children. During that time, we will focus not on a speedy recovery, but a thorough one.”

Kony 2012 prompted a litany of responses from critics, including a video from Ugandan Prime Minister Amana Mbabazi that corrected what he called dated information about Uganda.

“The Kony 2012 campaign fails to make one crucial point clear. Joseph Kony is not in Uganda,” he said in a nine-minute video posted on YouTube.

“You may all be assured that the Government of Uganda is acutely aware of the grievous damage which has been caused to our people by Joseph Kony and the Lord’s Resistance Army. We do not need a slick video on YouTube for us to take notice.”
